William Palmer, 2nd Earl of Selborne

The Earl of Selborne by Leslie Ward, 1901.

Selborne was assistant private secretary to the Chancellor of the Exchequer, Hugh Childers, from 1882 to 1885, when he was elected Liberal Member of Parliament for East Hampshire. Like his father, he became a Liberal Unionist in 1886 when William Ewart Gladstone proposed Irish Home Rule. He retained his seat till 1892, when he was elected for Edinburgh West. In 1895 he was appointed Under-Secretary of State for the Colonies by his father-in-law Lord Salisbury, where he became junior to the Colonial Secretary Joseph Chamberlain. During the difficult period before the outbreak of the Second Boer War he progressed rapidly.[2]

In November 1900 Selborne was sworn of the Privy Council[3] and made First Lord of the Admiralty under Salisbury, with a seat in the cabinet, an office he retained when Arthur Balfour became Prime Minister in 1902. In 1905 he succeeded Lord Milner as High Commissioner for Southern Africa and governor of the Transvaal and Orange River colonies. He assumed office at Pretoria in May of that year. He had gone out with the intention of guiding the destinies of South Africa during a period when the ex-Boer republics would be in a transitional state between crown colony government and self-government, and letters patent were issued granting the Transvaal representative institutions.[2]

But the Liberal Party came into office in Britain the following December, before the new constitution had been established, and, the decision was now taken to give both the Transvaal and Orange River colonies self-government without delay. Lord Selborne accepted the changed situation, and the experiment proved successful. He ceased to be governor of the Orange River Colony on its assumption of self-government in June 1907, but retained his other posts until May 1910, retiring on the eve of the establishment of the Union of South Africa.[2]

The despatch, dated 7 January 1907 and known as the Selborne Memorandum, in which he reviewed the situation in its economic and political aspects, was a comprehensive statement of the dangers inherent in the existing system and of the advantages likely to attend union. The document had in fact been compiled by Lionel Curtis and other members of Milner's Kindergarten. The force of its appeal had a marked influence on the course of events, while the loyalty with which Lord Selborne co-operated with the Botha administration was an additional factor in reconciling the Dutch and British communities.[2]

He returned to England with his reputation, according to the 1911 Encyclopædia Britannica, "as a statesman enhanced by the respect of all parties, and with a practical experience, second only to that of Lord Milner, of British imperialism in successful operation." His experience made him a valuable ally in the movement among the Unionist party at home for Tariff Reform and Colonial Preference, to which he could now give his full support.[2]

In 1915 Selborne returned to government during the First World War when he became President of the Board of Agriculture in the war time coalition of Liberal prime minister H. H. Asquith. He resigned from Cabinet in June 1916 because of Lloyd George's handling of the botched Home Rule negotiations (May–July) and the Prime Minister's failure to bring Lloyd George to task while the negotiations were still in progress. Selborne did not hold high political office again. The Selborne Committee on Church and State from 1914 to 1916 was chaired by Lord Selborne.[4]

Apart from his political career Selborne served as Master of the Worshipful Company of Mercers in 1910 and 1933, as his father had done before him, in 1875. In 1916 he was elected a member of the Society for Psychical Research. He was also Warden of Winchester College between 1920 and 1925 and High Steward of Winchester between 1929 and 1942. He was made a Knight of the Garter in 1909.
